San Luis Valley

San Luis Valley

The San Luis Valley is an extensive alpine valley in the United States states of Colorado and New Mexico covering approximately 8,000 square miles and sitting at an average elevation of 7500 feet above sea level. The valley sits atop the Rio Grande Rift and is drained to the south by the Rio Grande River, which rises in the San Juan Mountains to the west of the valley and flows south into New Mexico. The valley is approximately 122 miles (196 km) long and 74 miles (119 km) wide, extending from the Continental Divide on the northwest rim into New Mexico on the south.

Geography

The San Luis Valley is generally considered to comprise six Colorado counties: Saguache, Alamosa, Rio Grande, Conejos, Costilla and Mineral. The principal towns are: Alamosa, Monte Vista, Del Norte, South Fork, Saguache, Center, Fort Garland, San Luis, Antonito, La Jara, Capulin, Manassa, Sanford, Crestone, Villa Grove, Hooper, Mosca, San Acacio, Colorado and a number of smaller locations, some ghost towns. A few other counties of Colorado have some land in the Rio Grande Basin including Archuleta County, Hinsdale County and San Juan County.

The Sangre de Cristo Mountains form the eastern border of the valley. Blanca Peak is prominent at the southern end of the northernmost section of the mountains, which is known as the Sangre de Cristo Range. There are several passes, with elevations between 9,000 and 10,000 feet (2,700 and 3,000 m), giving access to the valley. La Veta pass, through the Sangre de Cristo Mountains, is used by US Highway 160 and by the San Luis and Rio Grande Railroad (formerly a branch of the Denver & Rio Grande Western) tracks. Other passes used historically were Medano, Mosca and Sangre de Cristo Passes. Otto Mears was the engineering genius behind the construction of a railroad link that ran from the Arkansas River, over Poncha Pass (at the north end of the valley), and into the San Luis Valley.

The Great Sand Dunes is a famous feature of the valley. It lies directly to the west of the Sangre de Cristo Mountains. The dunes can reach 750 feet high. The Great Sands Dunes National Park and Preserve is now in place to protect both the dunes and the numerous archeological sites found in the area. The natural valley aquifer is close to the surface in this part of the valley, and helps with maintenance of water levels in the San Luis Lakes, just to the west of the sand dunes.

Elevation rises as you go north in the valley to Poncha Pass, used now by US Highway 285 and historically by the narrow gauge tracks of the Denver and Rio Grande Railroad.

History

The San Luis Valley was long part of the lands of the numerous and powerful Ute Indians. The Valley was the first portion of Colorado to be settled by people of European descent. The area was administered as part of the Spanish, later Mexican, province of Nuevo Mexico until the area was purchased by the United States as part of the Treaty of Guadalupe Hidalgo in 1848. Extensive settlement began in the Valley, again primarily by Hispanic farmers and ranchers from New Mexico in the 1850s. The history of the post-war US military presence in the Valley is preserved at Fort Garland and other sites in the Valley, which became part of the Territory of Colorado in 1861. Today, the Valley has the largest native Hispanic population in Colorado; many families are directly descended from the original New Mexican settlers. The original Ute population was confined to the Southern Ute and Ute Mountain Indian reservations in the late 1800s.

Land ownership and management

About 50% of the 2,000,000 acres (8,000 km²) in the San Luis Valley is privately owned. Much of the land in the Valley floor itself was originally part of large Spanish and Mexican land grants.

500,000 acres (2,000 km²) on the borders of the valley (generally adjacent to National Forest Lands) are managed by the Bureau of Land Management, BLM, a division of the United States Department of the Interior. This land is usually leased to neighboring ranches for grazing for a nominal fee. Part of the value of a ranch is its continuing lease of BLM or National Forest lands.

Public lands in the mountains surrounding the San Luis Valley are generally part of the Rio Grande National Forest and are managed by the United States Forest Service.

Large areas of private lands have either been subdivided into subdivisions of small "ranch" lots or have been sold or donated to the Federal government and make up portions of the Great Sand Dunes National Park and Preserve, other wildlife preserves, and various state wildlife sites.

Agriculture and wildlife

Agriculture in the San Luis Valley is generally concentrated around the Colorado towns of Alamosa, Monte Vista and Center. Principal crops include potatoes, head lettuce and barley. Less favored areas with a shorter growing season and less access to water rights tend to be devoted to alfalfa and grazing. Broad areas, especially in Saguache County, Colorado have a high water table or are even flooded part of the year. Uncultivated land is often covered with "chico", low brush such as rabbitbrush, greasewood and other woody species. Cropland is typically irrigated with large (1/4-mile diameter) center-pivot irrigation systems, and a common feature of the Rio Grande Delta area where the Rio Grande enters the valley are large piles of potato-sized rocks screened from the soil.

The area supports a wide variety of wildlife. Sandhill cranes migrate through the valley every spring and fall. The Monte Vista Crane Festival takes place in March, centering on the wildlife refuge located six miles south of town. Occasionally, a whooping crane can be spotted among the thousands of grey sandhills. The valley is a flyway for many migrating birds including avocets, bald eagles, goldfinches, and a plethora of hawk varieties.

Artistic community

There are over 500 known artists living in the San Luis Valley as evidenced by an onging directory maintained by Monte Vista artists' group, The Art Thing, [ [http://theartthing.net The Art.Net] ] The Art Thing's membership boasts several nationally recognized artists working in various media. Monte Vista is also home to the [ [http://www.montearts.com montearts.com] ] Monte Arts Council as well as several festivals and an art tour that attracts artists from as far away as California and North Carolina.

The San Luis Valley is home to four active live theaters, two at Adams State College, The Creed Repertory Theater and Rocky Mountain Stage in Monte Vista. In August there are two major Music Festivals, the Crestone Music Festival and Spanish Trails Music Festival and Mexican Rodeo. Music in the valley has two well known sponsors in the South Fork Music Association and the Alamosa Live Music Association.

Economy

Predominantly agricultural in nature, the area is also one of the poorest rural areas of Colorado, and is a net exporter of its children. Tourism has become a more important part of the economy in recent years, coupled with attempts to establish the area as a retirement community. Adams State College, a government-run four-year college at Alamosa, with approximately 2,500 resident students, is the major educational institution in the Valley. San Luis Valley Regional Medical Center, a full service Acute-Care hospital and specialty physician clinic is the largest employer in the Valley with over 600 employees. The arts are becoming an increasing force in developing the economy of the San Luis Valley.
